It is an interesting piece of trivia, for sure. It would be dangerously easy to draw false conclusions from the chart alone (ie: interest rates are lower today than they were in the mid 90s, so it must have been harder to buy a home in the mid 90s), but it has me interested enough to look into the effects of the relative workforce/economic climates of the time periods. I'd also be very interested to see a chart that shows the non-adjusted minimum wage as compared to the value of the dollar against foreign currencies across the same time period.

The main idea I get from it is, while minimum wage has increased over the last 60 years, the rest of the economy has grown much faster, making it harder to survive on $8 an hour in 2014 than it was to survive on less than $2 an hour in the late 60's.

You're using its absolute peak value, a possible statistical outlier, to make that assertion. Looking at this chart, the value of the minimum wage (in 2012 dollars) is as high as it's been in the last 30 years (save the 2010 spike).
